The invention discloses a variable-transmission-ratio gearbox for a railway vehicle and the vehicle. The gearbox comprises a gearbox body, an input shaft, an output shaft and a displacement mechanism. The input shaft is fixedly connected with at least two driving gears; the output shaft is rotationally connected with at least two driven gears, the driven gears are meshed with the driving gears in a one-to-one correspondence mode, and first concave-convex structures are arranged on the end faces of the driven gears. The displacement mechanism comprises a force transmission disc, a force transmission sleeve and a drive plate assembly, the force transmission disc is fixedly connected with the output shaft, and outer teeth are arranged on the periphery of the force transmission disc; inner teeth matched with the outer teeth are arranged on the inner circumference of the force transmission sleeve, the force transmission sleeve can move in the axial direction of the force transmission disc, and a second concave-convex structure used for being matched with the first concave-convex structure is arranged on the end face of the force transmission sleeve. The drive plate assembly is used for driving the force transmission sleeve to move axially, so that the force transmission sleeve is selected to be matched with the driven gear. The variable-transmission-ratio gearbox for the railway vehicle is designed according to the gearbox of the railway vehicle, and different transmission ratios are achieved through meshing of different gears of the input shaft and the output shaft.
